An auxiliary electric power device, which is coupled to a prime mover, provides electric power to convenience outlets, appliances, and heating cooling units. Based on a mode of a transmission coupled to the prime mover, one of a plurality of control schemes is selected to control the power provided by the auxiliary electric power device.

Engine transmission-dependent control for electric auxiliary power generation

A fuel cell module includes a fuel cell stack configured to produce an electrical output, power electronics circuitry configured to convert the electrical output of the fuel cell stack into a regulated output of the fuel cell module, module control electronics circuitry configured for communications within the fuel cell module and further configured for communications with master control electronics circuitry external to the fuel cell module, and a structure configured to connect together the fuel cell stack, the power electronics circuitry and the module control electronics circuitry as part of the fuel cell module that is unitary, and further configured for the unitary fuel cell module to be insertable as a unit into a multi-module system chassis.

Modular fuel cell systems and methods

A storage and retrieval apparatus for objects with looped openings, the apparatus being flexible and made of metal, the apparatus characterized in having first and second arms, the first and second arms each having an upper end and each having a lower end, the apparatus having a body with first and second ends, the first end of the body connecting with the lower end of the first arm, the second end of the body connecting with the lower end of the second arm, the body having a shape, the shape of the body urging the first and second arms toward each other with a first spacing therebetween, the upper end of the first arm defining a first tip, the upper end of the second arm defining a second tip, the first tip and the second tip forming a space wider than the first spacing.

A transducer mechanism has a stacked piezo electric actuators driving arms rotating in different directions and having a structure such that the arms remain generally parallel to each other. A flexible member may be attached to the arms to obtain an extended stroke in a direction perpendicular to the axis of movement of the actuators.

A valve comprises a valve body having a fluid inlet and fluid outlet, a valve seat located in the valve body between the fluid inlet and a fluid outlet, a valve member movable towards and away from the valve seat for controlling the flow of fluid from the fluid inlet to the fluid outlet, and a PTC heater in thermal contact with the valve seat for heating the valve seat. The heater is integrated in the valve in a manner where the valve seat is used as an electrical conductor to facilitate operation and assembly of the valve, and a unique valve construction is provided for enabling self-draining to avoid accumulation of water or other liquid in the valve that might negatively impact performance of the valve.

Valve with freeze-proof heated valve seat

A filter element and assembly for fluid applications which require a purging of air, and particularly for applications where the filter element is horizontally oriented (side loaded), where the filter element is rotationally positioned relative to the housing such that a vent orifice is properly located for venting air from the filter element as the element fills with fluid. The housing includes a cylindrical body with a closed end a threaded open end, and a threaded, cup-shaped cover which is screwed down onto the housing. The filter element and housing include i) cooperating retaining devices which temporarily couple the filter element to the housing cover when the element is initially inserted into the housing and the cover is initially screwed onto the housing; and ii) cooperating orientation devices which rotationally orient the filter element in the housing as the housing cover is further and fully screwed down onto the housing.

Filter element with vent orifice and assembly therefore

A filter assembly includes housing enclosing a replaceable filter element. A support core is provided in the housing, and includes an extension and locking assembly. The element includes a ring of filtration media with a pair of end caps. The first end cap includes a central opening to receive the support core. The extension and locking assembly prevents the cover of the housing from being attached to the housing body without a proper filter element installed. The extension and locking assembly includes a bypass member and a locking member, which are in locking engagement when an element is absent in the housing. The second end cap includes internal protrusions which engage the locking member when the filter element is installed to disengage the bypass member from the support core, and allow the element to be inserted and the cover to be installed.

A filter element removably located in a housing having a central valve structure. The element has an end cap with a valve actuating portion. The valve actuating portion includes a cylindrical portion and an annular base projecting radially inward from the cylindrical portion. The valve actuating portion includes a plurality of thin, flat keys spaced around the annular base and projecting radially inward from the cylindrical portion and axially outward from the base. The keys engage the valve structure in the housing when the element is installed, and open up a flow passage through the housing.
